Mud desander for Solids Control system
published date: 12-13-2019
Mud Desander is widely used in the purification and recycling of mud for the construction hydro power, continuous concrete wall, slurry shield tunnel, etc. The drilling mud cleaning equipment is increasingly becoming a necessity of civilized construction since it not only can cut down construction cost, but also can reduce the pollution of the environment.

How the mud cleaning system work
1. The circulation of the drilling fluid is maintained by a circulating mud pump. The high-pressure drilling fluid discharged from the mud pump passes through the ground high-pressure manifold, riser, hose, faucet, kelly, drill pipe, drill collar to the drill bit, and sprays from the drill nozzle. Out to clean the bottom of the well and carry cuttings.
2. The annular space formed along the drill string and the well wall (or casing) flows upwards, and after reaching the ground, flows into the mud pool through the discharge pipeline, and then returns to the upper pool through various solid control equipment, and finally enters the mud pump cycle. Use again. The various pipe fittings and equipment through which the drilling fluid flows constitute a complete drilling fluid circulation system.
Use hydro-cyclone remove sand from mud water
Mud Desander is mainly composed of a hydro cyclone desilter. Under the pressure of muddy water, it enters the cyclone separation system through the pipeline at high speed and makes a swirling motion in the cylindrical wall shell of the cyclone. The coarse particles are thrown to the wall and gradually move downward under the action of gravity. The bottom is discharged. The fine particles move to the wall at a lower speed and are discharged by the central flowing liquid from the upper central overflow pipe to make the mud coarsely subdivided.
